摘要
在本文中，我们报告了一种通过简单的两步碳化工艺从麻布废料中获得高产率含石墨烯生物碳的方法。第一步是在 600 °C 下对原料进行碳化，然后进行球磨，最后在 1200 °C 下使用 KOH 进行石墨化。对所获得的生物石墨烯和商用石墨烯进行比较分析后发现，麻布基石墨烯具有更优越的石墨烯特性。值得注意的是，这种生物基石墨烯表现出非常优异的特性，如 BET 表面积非常高，达到 1021 m²/g，拉曼光谱中缺陷与石墨烯的比率低至 0.12，总体产量达到 19%（重量比）。这些发现凸显了麻布废料作为高质量石墨烯合成的可持续前驱体的潜力及其在各种应用领域的潜力。
Graphene-containing biocarbon from burlap waste: Property comparison with commercial grade graphene nanoplatelets
In this paper, we report a method for achieving high-yield graphene-containing biocarbon from burlap waste through a simple two-step carbonization process. The first step involves feedstock carbonization at 600 °C, followed by ball milling and then graphitization at 1200 °C using KOH. A comparative analysis between the obtained bio-graphene and commercial graphene revealed superior graphene properties of the burlap-based graphene. Notably, this bio-based graphene exhibited exceptional characteristics such as a very high BET surface area in the range of 1021 m²/g, low defect-to-graphene ratio of 0.12 in the Raman spectra, and an overall yield of 19% wt. These findings highlight the potential of burlap waste as a sustainable precursor for high-quality graphene synthesis and its potential for various applications.
